Yet, I also have been told by fellow RS travelers and others that
there are times (not always) that the begging has been very
aggressive, and another instance when a group of 4 young men acted
more in a threatening, shakedown manner rather than in a
requesting/begging fashion. People on the train felt unsafe and
trapped with no recourse---was it unsafe? No, bec nothing happened,
but it felt threatening, not something any of us are longing for.
SuzieeQQ, that's probably fairly accurate. It's like this. If you're in a good mood, not tired or jetlagged, these minstrels or wastrels--depending on your point of view--are amusing and good for a story to be told when you get home. If you have bags, or the CV is crowded, or you're at the end of a long day, it's more like who wants to put up with that crap? Someone gets in my face when I'm like that & my patience level is nil, chances are I'll get confrontational, which probably wouldn't end well for either of us.
We rode 4 times during the day in early March, and it was fine. A couple of drunkards, a couple on-off bongo/squeezebox 'musicians' that raised a racket, and they were largely ignored by everyone, us included. But when we originally arrived at Naples Centrale from Rome, we hired a private driver to take us to Sorrento, costing us about 85 Euro more than if we had taken the CV. In hindsight, money well spent.
Take your choice.
